초록
실크 단백질과 녹색 형광 단백질을 결합한 순수 단백질 기반 녹색 형광체의 구현과, 산화티타늄 나노 입자에 의한 형광 증폭 현상을 보고한 다. 실크 단백질은 인간에게 다양한 이점을 제공하는 소재로서, 다양한 마이크로/나노 구조 형성 가능성과 투명한 성질을 가지고 있어 광학소 재로서의 활용 가능성 또한 높다. 본 연구에서 제작한 소재는 강한 녹색 형광을 띠고 있으며, 산화티타늄 나노 입자에 의해 녹색 형광이 7.5배 증폭되는 것을 확인하였다.
Abstract
We report a purely protein-based platform for green fluorescence by mixing silk protein with green fluorescence protein (GFP), and also report its enhancement by the incorporation of TiO 2 nanoparticles. The TiO 2 nanoparticles eployed have diameters of 100 and 300 nm, with a significant increase in fluorescence (by a factor of 7.5) observed when introducing 300-nm TiO 2 nanoparticles. Furthermore, an increase in particle distribution density is found to enhance fluorescence amplification. These research findings suggest that protein-based fluorescent films can be enhanced by the characteristics of nanoparticles, opening up new possibilities in the fields of optics and fluorescence applications.
